ML145159 Datasheet | LANSDALE Semiconductor

.. Serial-Input PLL Frequency Synthesizer with Analog Phase Detector INTERFACES WITH DUAL- MODULUS PRESCALERS Legacy Device: Motorola MC145159-1 The ML145159 has a programmable 14- bit reference counter, as well as fully programmable divide- by- N/divide- by- A counters. The counters are programmed serially through a mon data input and latched into the appropriate counter latch, according to the last data bit (control bit) entered. When bined with a loop filter and VCO, this device can provide all the remaining functions for a PLL frequency synthesizer operating up to the device's frequency limit. For higher VCO frequency operations, a down mixer or a dual- modulus prescaler can be used between the VCO and the PLL. - Operating Temperature Range: TA - 40° to 85°C - Low Power Consumption Through Use of CMOS Technology - 3.0 to 9.0 V Supply Range - On- or Off- Chip Reference Oscillator Operation - patible with the Serial Peripheral Interface (SPI) on CMOS MCUs - ÷ R Range = 3 to 16383 - ÷ N Range = 16 to 1023, P A Range = 0 to 127 - High- Gain Analog Phase Detector - See Application Note AN969 Note: Lansdale lead free (Pb) product, as it bees available, will be identified by a part number prefix change from ML to MLE.
